This paper investigates the effects of the omission of relevant variables from the statistical model on cointegration analysis, proposed by Johansen (1988, 1991). We show that underspecification of the statistical model leads to either failure in detecting cointegration or underestimation of the...

We investigate analytically and via Monte Carlo simulations the effects of the inclusion of irrelevant variables in the statistical model, on the cointegration analysis of Johansen (1988, 1991). We show that overspecifying the statistical model does not affect inference about the cointegrating...
